Bonjour , je cherche de l’aide pour UNE question .
( calculer le pourcentage massique en nitrate d’ammonium de l’engrais étudié) .
Voici ce que j’ai trouvé pour les précédentes questions ;
- Equation : NH4+ + HO- -> NH3 + H2O
- VE= 14 mL
- CA= cb* Ve/Va = 3,00*10^-1 * 14 /10
Donc CA = 0.14 mol/L
Merci d’avance !
